Are 7kW of laser power enough to allow communications at distances similar to that between Earth and Mars at their farthest? And at speeds 100x that of equally powered radio transmissions?

#NASA seems to have proven it is:

“Our hybrid antenna has been able to successfully and reliably lock onto and track the #DSOC downlink since shortly after the tech demo launched,” said Amy Smith, #DSN deputy manager at JPL. “It also received #Psyche's radio frequency signal, so we have demonstrated synchronous radio and optical frequency deep space communications for the first time.”

2023 was a big year for laser communications at #NASA! It saw the first bi-directional laser communications relay with the #ISS performed by the #LCRD mission (at over 1 Gbps), a 267 Mbps downlink from deep space (19 million miles away) by the #DSOC mission, and 200 Gbps throughput on a laser link with a LEO orbiting spacecraft by the #TBIRD mission.

Psyche – from Greek mythology to Greek mountain tops

ESA will participate in NASA's Deep Space Optical Communication (DSOC) demonstration in 2025.

To select a suitable site for ESA’s ground infrastructure, the team searched for the most suitable optical telescopes in Europe; the 2.3 m Aristarchos telescope, located at an altitude of 2340 m at the Helmos Observatory in Greece, checked all the necessary boxes.
